PURPOSE: The following script can be used to measure the nucleic acid helical parameters. It assumes that the helix axis coincides with the Z axis of the coordinate space. This is true for structures built using the Nucleic Acid builder in Discovery Studio but will likely not be true for structures from other sources. The parameters reported are Rise, Twist, X-displacement, Propeller Twist, Inclination and Roll.
